Description:
The purpose of this research program was to determine the effect of the addition of powdered activated carbon (PAC) to refinery activated sludge systems. Bench-scale and full-scale tests were performed. A wide range of PAC concentrations and sludge ages were evaluated. Bench-scale activated sludge systems were designed and constructed. The bench-scale units were initially operated to determine the conditions of the full-scale test. Additional bench-scale tests were performed to evaluate conditions impractical to meet during the full-scale testing. A moderate enhancement of COD removal was observed. PAC addition had little effect upon the removal efficiency of other contaminants or the toxicity of undiluted effluents. An economic analysis of PAC addition was performed.
